The Great Potter is perfect. He makes no mistakes.
I am not a potter but one month in my early 20s I took a weekly pottery course. It was really important to get all the air bubbles out of the clay before putting it on the pottery wheel where the shaping happens, where the potter's hands get on the clay. If a bump in the clay is discovered while on the wheel a good potter will change his plan and use way it is to form another shape.
With human potters, depending on how experienced they are, the fault may lie with them if the clay doesn't turn out. With God, the fault is in us. He is the perfect master potter. He is beyond creative. He sees possibilities where we can only see failure. We might see how badly we messed up and think it's over. God thinks something like, Ah, well then, let's do this with your life. Let's use that failure to make an intricate design in the clay.
We are part of the process. We aren't robots. What we do does affect what God does in our lives.
Later in this chapter God says He is like the potter. He says that if a nation is doing evil and He proclaims that He is going to bring judgment on that nation, that if that nation repents and turns from evil He will relent, stop the judgment. He also says it can happen in the reverse. If He was going to bless a nation big time but then the nation turns from Him, He won't send those blessings.
How much more in our personal lives can this happen! If we jump off the potter's wheel we take ourselves out of God's hands. No good can come from this. Clay that leaves the potter's hands before it is finished is just a lump of clay. Pretty ugly really and useless.
Don't leave the Potter's hands. Trust Him. He has a plan. Let Him do it. Yield to Him. You won't regret it (though it will be very difficult and possibily painful at times).
